| Abstract: | Gibberellins form an important group of plant growth hormone, which have many biological activities. Its structure was determined by X-ray single crystal diffraction, no complete assignment of 1H and 13C NMR spectrum of the compounds have been reported. In this paper, all the 1H and 13C NMR chemical shifts of methyl gibberellate (2), 13- acetoxygibberellin A1 methyl ester ( 3 ) and its 3-epimer (4) were assigned by 1H-1H COSY , 13C-1H COSY, NOESY and DEPT, and their relative configurations were discussed. |
